Looking at the other side of the coin, I used to live and work in a small rural town in central CA. One day there was a pretty good earthquake (6.5). In addition to destroying almost all of the downtown section, a lot of houses were flattened ot knocked off of their foundations. A lot of residents lived several miles out of town, up a narrow canyon that had a creek winding down it. Two lane road, lots of bridges over the creek, most of which were destroyed. Many of the folks living up there did so because they wanted to be independent. So, within three days, many of them were screaming for food and water, claiming that they were starving to death. So my department chopper, the only public rotarywing aircraft in the enire county, was pulled from more important details to fly some burgers and fries to those hardy canyon dwellers. Imagine, running out of food in three days!!!
